SPECIFICATION forming part of Letters Patent No. 566,590, dated August25, 1896.y Application iiled December 5, 1894. Renewed January 4, 1896.Serial No. 674,391. (No model.)

To @ZZ whom, t may concern:

Be it known that I, ERNST LINDNER, a citizen ot' thellnited States, anda resident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Gas-Cocks, of whichthe following is a specification.

My invention relates to gas-cocks, and particularly where the cock iscombined with the coupling-piece, which is adapted to be connected tothe pipe supplying the gas and also to the bracket carrying the burner.

The object of my invention is to simplify and chea pen the manufactureof such devices, wherein there is combined with the coupling-piece alateral branch adapted to connectwith the tubing of rubber for supplyinggas to a drop-light, gas-heater, or the As usually constructed the cockcontrolling the supply or' gas through the lateral branch is placedwithin a casing or globe formed as a part of the lateral branch. Thisincreases the cost and diiiiculties of manufacture, since it requires,in addition to the globe-casing between the coupling ends of the device,and from which casing the latter branch extends, an independentglobe-casing in said lateralbranch to receive the cock controlling thegas supplied through said branch. By my invention I dispense with one ofthese globe-casings, utilizing' the globe-casing between the couplingends of the device for the cock regulating the supply of gas to thelateral branch. In the manufacture of my gascock all the parts are madefrom a solid bar or rod of metal on a suitable lathe, no castingwhatever being made use of, and hence expense of finishing the device bypolishing, ttc., is avoided.

jin embodiment ot my invention is shown in the accompanying drawings, inwhich like parts are indicated by like letters of reference in all theviews, and wherein- Figure l is a viewln perspective showing agas-bracket provided with niy improved gas-cock. Fig. 2 represents avertical sectional view through the globe or shell between the couplingends of the device and longitudinally through the lateral branch, thegate-key and its thumb-piece being in side elevation. in this view, aswell as in Fig. l7

the thumb-piece is shown at the top of the casing, though when in use itwill ordinarily be at the bottoni. Fig. 3 is a horizontal longitudinalsectional view on the line 2 2 of Fig. 2.

Referring to the drawings, o indicates' the central enlargement orglobe-casing of the device Z) a cou'pling end, which is adapted toconnect with the gas-supply pipe and is screwthreaded internally, asshown, for that purpose, and c the coupling end externally screwthreadedand adapted to receive the bracket provided with the gas burner orburners. The casing a is provided centrally and vertically with thevalve-seat, which is tapered, as shown, in the usual ina-nner to receivethe tapered gate-key d, and which latter is secured within its seat by anut c or equivalent means.

That portion of the gate-keyf outside of the casing is of a roundconfiguration and is provided with a thunib-piece g of any suitabledesign. The shank d of the gate-key is also provided outside of thecasing with a stop h, whereby the revolving motion of the gate-keywithin the casing is controlled and limited. The shank d is likewiseprovided with a passage through it laterally, as indicated at 1'.

The casing a is formed with the lateral eX- tension k, having a channelthrough it conimunicating at its inner end with the coupling end b, andthe outside surface of the lateral branch or extension 71: may becorrugated or similarly formed to facilitate the retention of the rubbertube thereon. The casing o is also provided with a through-passage linthe rear of the wall of that portion of the casing through which thevertical valve-seat is made. The passage l connnunicates with thecoupling ends o c, and is adapted to supply a continuous llow of gas tothe burner on the bracket which is secured to c, the cock controllingthe supply to the burner being on the bracket. The supply of gas to thelateral branch 7e is controlled by the suitable adjustment of the key dwithin the casing. ln both views the key d is adjusted to permit theilow of gas through the lateral branch k.

It is obvious that by reversing the key its lateral opening 'L' will beout of register with the passage through the lateral branch k and thesolid portion of the key will etfectually close such passage.

IOO

By my present invention, whereby the means for controlling the supply ofgas to the lateral branch are located within the casing a, through whichalso extends the passage for the supply of gas to the burner on thebracket, I produce a compact and cheap fixture, all

the parts of which, as before stated, beingl 2. A gas-cock consisting ofa central globe or casing, provided with coupling ends and a lateralbranch or extension, the latter having a through-passage communicatingwith one of said coupling ends and the casing having a through-passagecommunicating with both coupling ends and a central valve-seat, incombination with a gate-key fitted within the seat of the casing andprovided with a lateral opening adapted to register with the passage-Way through said lateral branch, substantially as set forth.

Signed at New York, in the county of New York and State of New York,this 13th day of November, A. D. 1894.
